· JVASP-46046· Li4B2O5

Li4B2O5 is a lithium borate ceramic compound that combines lithium oxide and boron oxide in a stoichiometric ratio, forming a crystalline inorganic material. While primarily used in research and specialized applications, lithium borates are valued in solid-state battery electrolytes, optical coatings, and glass-ceramic systems where lithium ion conductivity and thermal stability are critical. This compound represents the family of lithium borate ceramics—materials of growing interest for solid electrolyte membranes in next-generation energy storage and high-temperature optical applications where conventional silicate glasses fall short.
